“…Fase padat dan cair dari aerosol terdiri dari bakteri, elemen darah, virus, dan partikel organik dari jaringan, gigi, saliva, dan debris. Jumlah kontaminasi aerosol tergantung pada kualitas saliva, sekresi hidung dan tenggorokan, darah, plak gigi, dan ada tidaknya infeksi gigi (Ge et al, 2020). Oleh karena itu aerosol dan droplets yang menyebar sangat berbahaya dan berpotensi menularkan penyakit.…”

Latar Belakang: Petugas layanan kesehatan gigi dan mulut rentan terpapar infeksi berbagai penyakit dari pasien. Rongga mulut penuh dengan bakteri. Droplets dan aerosol dari cairan mulut pasien dapat menjadi media penularan penyakit. Extraoral suction unit (EOSU) dibutuhkan untuk membantu mengendalikan sebaran aerosol selama layanan kesehatan gigi.Tujuan: Penelitian ini bertujuan untuk membandingkan unjuk kerja extra oral suction unit lokal dengan produk komersial sebagai pembanding.Metode: Desain penelitian ini menggunakan metode deskriptif observasional dengan rancangan cross sectional. Sampel penelitian berupa alat penyedot aerosol hasil rancangan tim peneliti Universitas Gadjah Mada Merk D yang dibandingkan dengan dua produk komersial dari luar negeri Merk A dan B, satu alat produk dalam negeri Merk C. EOSU diuji di klinik gigi dengan prosedur serupa layanan sesungguhnya. Pengujian yang dilakukan adalah mengukur kapasitas hisap, tingkat kebisingan, sebaran aerosol dan angka kuman.Hasil: Extraoral suction unit produk buatan luar negeri (Merk A) menunjukkan unjuk kerja yang paling baik karena sebaran aerosol di sekitar lokasi kerja paling sedikit. Produk Merk D mempunyai unjuk kerja di bawah produk Merk A namun masih lebih baik dibanding produk buatan luar negeri lainnya (Merk B) dan produk dalam negeri lain (Merk C)Kesimpulan: Extraoral suction unit lokal mempunyai kapasitas serupa dengan produk komersial dan menjanjikan untuk diproduksi massal.

“…8 Conversely, particles exceeding 50 μm in diameter typically lead to the formation of splatter patterns and are not inhalable, rendering them less hazardous. 6,9 Therefore, the reduction of water spray quantities in various dental procedures holds paramount importance in mitigating the risk of viruses and bacteria transmission within the field of dentistry. 1,2,10 The utilization of water-air spray cooling in dental rotary tools results in the emission of aerosols that contain various microorganisms, such as viruses, bacteria and fungi.…”

Background. Maintaining biosafety in dental practice involves the effective elimination of aerosols produced during dental treatment.Objectives. To assess the quantity of aerosols and aerobic bacteria in the air during the treatment of caries. Materials and methods.The study involved 60 patients with a total of 60 molar teeth (n = 60) in the mandible who were divided into 2 groups based on caries treatment method. Group 1 (G1, n = 30) received treatment with a conventional dental turbine (W&H Synea TA-98LC; W&H, Bürmoos, Austria), while group 2 (G2, n = 30) underwent treatment with an Er:YAG (erbium-doped yttrium aluminium garnet) laser (Light-Walker, Fotona, Slovenia). Measurements of aerosol particles between 0.3 μm and 10.0 μm near the operator's mouth were taken using the PC200 laser particle counter (Trotec GmbH, Schwerin, Germany). The number of aerobic bacteria in the air was determined using 60 Petri plates with a microbiological medium (Columbia agar with 5% sheep blood) and the sedimentation method. A control group (G3) was established to measure initial aerosol levels and initial total number of bacteria colony-forming units (CFUs) before each treatment.Results. In G1 (dental turbine), the median value of aerosol particles was 57,021 (42,568), while in G2 (Er:YAG laser), it was significantly lower at 33,318 (28,463-35,484) (p < 0.001). The median total bacteria count per cubic meter of air in G1 (conventional dental turbine + high volume evacuator (HVE)), G2 (Er:YAG laser + HVE) and G3 (control group before caries treatment) were 734 (420-988), 158 (96-288) and 48 (32-74), respectively, with a statistically significant difference between the groups (p < 0.001).Conclusions. The use of Er:YAG laser during caries treatment resulted in a 41.6% reduction in aerosol amounts and a 78.5% decrease in the total bacterial count (TBC) compared to treatment with a dental turbine.

“…Dental rotary instruments which use water-air spray cooling generate aerosols containing various types of microorganisms (viruses, bacteria, fungi) [1]. Reducing a minimal number of aerosols produced during dental treatment is essential, especially for establishing the biological safety of the workplace [2].…”

“…The key factor in decreasing the airborne transmission seems to be the reduction in the total amount of water spray and aerosol in the air in a dental office [3,4]. The standard systems for removing aerosols during dental procedures utilize a suction system, e.g., a salivary ejector and a high-pressure evacuator [1,3]. However, in a previous in vitro study, we utilized a customized high-pressure handpiece with a broader handpiece to reduce aerosol amount during caries treatment in a dental manikin mouth.…”

Background: Effective removal of aerosols generated during dental treatment is crucial for maintaining biosafety in dental practice. This study aimed to measure the aerosol amount and the number of aerobic bacteria in the air during caries treatment. Methods: The study involved 50 molar teeth (n = 50) in the mandible in 50 patients divided into two groups based on the type of a high-volume evacuator (HVE); G1 (n = 25) conventional HVE (EM19 EVO, Monoart® Euronda, Vicenza, Italy) and G2 (n = 25) a new, wider, customized HVE. The PC200 laser particle counter (Trotec GmbH, Schwerin, Germany) was used to measure aerosol particles in a range of 0.3–10.0 μm near the operator’s mouth. The study used 60 microbiological plates with a microbiological medium (Columbia Agar with 5% Sheep Blood) to check the number of aerobic bacteria in the air. Results: The mean value of aerosol particles in the G1 group (conventional HVE) was 54,145 ± 7915, while in the G2 group (test, wider evacuator) was lower and amounted to 32,632 ± 1803. (p < 0.001). The median total bacteria count in the air per cubic meter in control, G1 (HVE), and G2 (NEW-HVE) groups were 50 [36-60]; 772 [643-881]; 120 [92-139], respectively. (p < 0.05). Gram-positive cocci were the predominant bacteria in the plates: Micrococcus sp. (50%), Bacillus species (36.4%), Staphylococcus epidermidis (3.8%), Staphylococcus saprophyticus (3.8%). Conclusions: the application of the wider high-volume evacuator increases the air purity during caries treatment as well as the biological safety of a dental office.
